What is the commute from Johns Creek to Atlanta?

The drive from Johns Creek into Atlanta runs mainly along GA-400, with Peachtree Parkway feeding into it from most neighborhoods in town. How long that drive actually takes depends heavily on which specific Johns Creek street you start from and when you leave, since GA-400 backs up considerably closer to the Perimeter during rush hour.
